I was messing around with the Trajan (spelling?) Parthia scenario and managed to get Trajans expedition deep into Mesopotamia. We were crushing all opposition then had a big battle that wrecked all 3 legions. My question is if I return to a big base such as Antioch will these legions rebuild or are the destroyed units lost forever?

Also is it better to build a string of depots from each location to keep supply moving? I know it's harsh desert terrain but my armies that pushed next to Trajan's force started to run out of supplies half way to Mesopotamia.

Destroyed units must be created new (production), damaged ones can be replenished (replacements), both in the F2 tab, called in AJE dilectus by the latin word for recruitment.

Depots (receptaculi) help a lot to supply and replenish, if you put a damaged force in a region with a depot it will replenish faster than in a city without depot , look for details in the manual.

Regarding supply, when I was messing with NCP in the Peninsular War years ago, I remember that Ney's corps was completely destroyed in its way to Galicia in northwestern Spain (no cities, depots, well nothing in the way). Arrived Ney,... and his horse

Supply does not 'move' in AJE as it does in many other AGEOD games. Instead, it uses simply supply; which means, supply only exists in the region where it is generated. If you are adjacent to a supply source and have a wagon, you can draw supply from an adjacent supply source in addition to the region your force occupies. But supply never moves more than to an adjacent region.With simple supply it is important to count elements in each of your units. For a unit to rebuild, you not only need dilectus as Nikel mentions, you also need to be in a supply region with supply equal to or greater than the number of elements in your force.The Parthian scenarios are a supply challenge for both Rome and Parthia.

Nice thanks for the replies guys. Good thing I'm the Emperor because I destroyed 3 Legions in the desert. Returned to Antioch and had a new army waiting for me. Will have to play this one very carefully.

Another gotcha seems to be that newly captured provinces with low loyalty to your side don't generate supply at the rate advertised on the tooltip. Regional loyalty and national morale influence the actual supply output of a province - this is mentioned in the manual - but it isn't clear whether the game adjusts the supply value in the tooltip to reflect this.

I've managed to get Crassus well down into Parthia but he finds it hard to stay supplied even though he captures major cities.

The display is original supply status plus depots built. It does not reflect the rebuilding of capacity.

Often, slow methodical play for the Romans is a more secure way to win in the east. I just can not do that, so I make very fast moves and shuttle supply if quick sieges are not in the cards, but, of course, I often end up with poorly supplied forces.

The further down the Euphrates that Rome goes the harder it gets. Playing the Parthian side at the moment I'm building river boats to move supply up-river and then overland to my field armies.

BTW I've just found an online club that plays these games PBEM. That works really well. LOL, I bought half a dozen AGEOD games in a big sale but so far I've only played AJE. There's still many hours of play value left in that game alone.

That's my approach - play the AI first. If I can't do OK there, a real player will probably wipe the floor with me.The other problem is just getting familiar with the scenarios - especially the geography, supply points etc.

I could probably play CW2 without too much preparation because I know Richmond and Washington were the capitals. But the Thirty Years War.... I'd have to google which thirty years, let alone the where the campaigns were.
